When the doors are unlocked, the turn signals will flash
and the illuminated entry system will be activated. When
the doors are locked, the turn signals will flash and the
horn will chirp. Settings in the Uconnect system can
change to lights only, chirp only, or both.
Vehicles Equipped With Keyless Enter ‘n Go™ — Passive
Entry
If one or more doors are open, or the liftgate is open, the
doors can be locked. The doors will unlock again only if the
key fob is inside the passenger compartment.
All doors can be programmed to unlock on the first push
of the unlock button within Uconnect Settings
Úpage 157.
Key Left Vehicle Feature
If a valid key fob is no longer detected inside the vehicle
while the vehicle’s ignition system is in the ON/RUN or
START position, the message “Key Fob Has Left The
Vehicle” will be shown in the instrument cluster display
along with an interior chime. An exterior audible and visual
alert will also be activated to warn the driver.
The vehicle’s horn will rapidly chirp three times along with
a single flash of the vehicle’s exterior lights.
NOTE:
The doors have to be open and then closed in order for
the vehicle to check for the presence of a key fob; the
Key Left Vehicle feature will not activate until all of the
doors are closed.
 These alerts will not be activated in situations where
the vehicle’s engine is left running with the key fob
inside.
Replacing The Battery In The Key Fob
The recommended replacement battery is one CR2032
battery.
NOTE:
Customers are recommended to use a battery
obtained from Mopar®. Aftermarket coin battery
dimensions may not meet the original OEM coin battery
dimensions.
 Batteries contain harmful chemicals. Dispose old
batteries by placing them in correct containers
according to the law or by taking them to a dealership,
where they will be handled appropriately.
 Perchlorate Material — special handling may apply. See
www.dtsc.ca.gov/hazardouswaste/perchlorate for
further information.
 Do not touch the battery terminals that are on the back
housing or the printed circuit board.

1. Remove the emergency key by pushing the mechanical release button on the side of the key fob
with your thumb and then pulling the key out with
your other hand.

Emergency Key Removal

2. Insert a coin or a flat-blade screwdriver into the now exposed slot and carefully pry on both sides to
disengage the snaps. Gently remove the back cover
from the fob, being careful not to damage any of the
snaps.
3. Remove the battery by sliding the battery rearward in its pocket until the battery lifts up. Remove the
depleted battery from the battery pocket and dispose
appropriately.
4. Fit a new battery ensuring that the positive (+) side is facing upwards. Push the battery into the pocket until
it is firmly seated in place and secured under both
tabs.
5. Align the back cover into its original position and snap it back in place by pushing it against the fob until it is
seated all around.

Programming And Requesting Additional
Key Fobs
Programming the key fob may be performed by an
authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it cannot be
repurposed and reprogrammed to another vehicle.
 Only key fobs that are programmed to the vehicle elec -
tronics can be used to start and operate the vehicle.
Once a key fob is programmed to a vehicle, it cannot be
programmed to any other vehicle. Duplication of key fobs may be performed at an authorized
dealer. This procedure consists of programming a blank
key fob to the vehicle electronics. A blank key fob is one
that has never been programmed.
NOTE:

When having the Sentry Key Immobilizer system
serviced, bring all vehicle keys with you to an autho -
rized dealer.
 Keys must be ordered to the correct key cut to match
the vehicle locks.
KeySense Features — If Equipped
This feature provides the vehicle owner with the ability to
customize vehicle settings that can be applied to
determine the driving experience for other drivers of the
vehicle. The vehicle settings are protected by a unique
4-digit PIN, which the vehicle owner creates when
accessing the specific settings for the first time.
KeySense also has additional features that are always
enabled when the specific key fob is in use that cannot be
set by the vehicle owner. While this specific key fob is in
use, the vehicle will respond accordingly to the customized
vehicle settings and mandatory features. This includes enhanced driving assistance features, increased driver
alerts, and the locking of certain optional features. These
settings can be selected within the Uconnect system
Úpage 157.

KeySense Key Fob

KeySense Unique Splash Screen
At vehicle start-up, the KeySense splash screen should
inform the driver that the vehicle will be functioning in
KeySense mode when the KeySense key fob is in use.
Start Up Display Features

Unique splash screen graphic
 Telltale illuminated
 After unique splash screen, and after stored messages
are cycled, then start-up KeySense messages (Range &
Max Speed) are displayed
WARNING!
The integrated key fob contains a coin cell battery.
Do not ingest the battery; there is a chemical burn
hazard. If the coin cell battery is swallowed, it can
cause severe internal burns in just two hours and
can lead to death.
 If you think a battery may have been swallowed or
placed inside any part of the body, seek immediate
medical attention.
 Keep new and used batteries away from children. If
the battery compartment does not close securely,
stop using the product and keep it away from chil -
dren.
WARNING!
 Always remove the key fobs from the vehicle and lock
all doors when leaving the vehicle unattended.
 For vehicles equipped with Keyless Enter ‘n Go™ Igni -
tion, always remember to place the ignition in the
OFF position when exiting the vehicle.

SENTRY KEY
The Sentry Key Immobilizer system prevents unauthorized
vehicle operation by disabling the engine. The system
does not need to be armed or activated. Operation is
automatic, regardless of whether the vehicle is locked or
unlocked.
The system uses a key fob, keyless push button ignition
and a Radio Frequency (RF) receiver to prevent
unauthorized vehicle operation. Therefore, only key fobs
that are programmed to the vehicle can be used to start
and operate the vehicle. The system cannot reprogram a
key fob obtained from another vehicle. After placing the ignition in the ON/RUN position, the
Vehicle Security Light will turn on for three seconds for a
bulb check. If the light remains on after the bulb check, it
indicates that there is a problem with the electronics. In
addition, if the light begins to flash after the bulb check, it
indicates that someone attempted to start the engine with
an invalid key fob. In the event that a valid key fob is used
to start the engine but there is an issue with the vehicle
electronics, the engine will start and shut off after two
seconds.
If the Vehicle Security Light turns on during normal vehicle
operation (vehicle running for longer than 10 seconds), it
indicates that there is a fault in the electronics. Should
this occur, have the vehicle serviced as soon as possible
by an authorized dealer.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics
Úpage 312.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
If applicable, refer to the “Hybrid Supplement” for
additional information.
This feature allows the driver to operate the ignition switch
with the push of a button as long as the key fob is in the
passenger compartment.
The START/STOP ignition button has four operating
positions; three of which are labeled and will illuminate
when in position. The three positions are OFF, ACC, and
ON/RUN. The fourth position is START. During START, RUN
will illuminate.

START/STOP Ignition Button

CAUTION!
The Sentry Key Immobilizer system is not compatible
with some aftermarket Remote Start systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.

16GETTING TO KNOW YOUR VEHICLE
The push button ignition can be placed in the following
modes:
OFF
 The engine is stopped
 Some electrical devices (e.g. power locks, alarm, etc.)
are still available
ACC
 The engine is stopped
 Some electrical devices are available (e.g. power
windows)
ON/RUN
 Driving position
 All electrical devices are available (e.g. climate
controls, etc.)
START
 The engine will start (when foot is on the brake pedal)
The engine only runs with the ignition in the ON/RUN
ignition position, or from a Remote Start request.
In case the ignition switch does not change with the push
of a button, the key fob may have a low or depleted
battery. In this situation, a backup method can be used to
operate the ignition switch. Put the nose side (side
opposite of the emergency key) of the key fob against the
START/STOP ignition button and push to operate the
ignition switch.

Backup Starting Method
NOTE:

The key fob may not be detected by the vehicle Keyless
Enter ‘n Go™ system if it is located next to a mobile
phone, laptop or other electronic device; these devices
may block the key fob’s wireless signal and prevent the
Keyless Enter ‘n Go™ system from starting the vehicle.
 For the proper engine starting procedure, see
Úpage 111.
REMOTE START — IF EQUIPPED
If applicable, refer to the “Hybrid Supplement” for
additional information.
This system uses the key fob to start the engine
conveniently from outside the vehicle while still
maintaining security. The system has a range
of 328 ft (100 m).
Remote Start is used to defrost windows in cold weather
and to reach a comfortable climate in all ambient
conditions before the customer enters the vehicle.
NOTE:Obstructions between the vehicle and key fob may reduce
this range Úpage 312.
WARNING!
 When leaving the vehicle, always remove the key fob
from the vehicle and lock your vehicle.
 Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
 Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or others
could be seriously or fatally injured. Children should
be warned not to touch the parking brake, brake
pedal or the gear selector.
 Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave
the Keyless Enter ‘n Go™ Ignition in the ON/RUN
position. A child could operate power windows, other
controls, or move the vehicle.
 Do not leave children or animals inside parked vehi -
cles in hot weather. Interior heat buildup may cause
serious injury or death.
CAUTION!
An unlocked car is an invitation for thieves. Always
remove the key fobs from the vehicle and lock all doors
when leaving the vehicle unattended.
